Validation of an algorithm to determine the primary care treatability of emergency department visits

摘要: Objectives We propose a new claims-computable measure of the primary care treatability emergency department (ED) visits and validate it using nationally representative sample Medicare data. Study design setting This is validation study 2011–2012 claims data for 5% fee-for-service beneficiaries to compare measure9s performance Ballard variant Billings algorithm in predicting hospitalisation death following an ED visit. Outcomes Hospitalisation within 1 day or 1 week visit; 1 month Results The Minnesota strong predictor hospitalisations deaths, with similar better than most commonly used existing assess severity visits. Billings/Ballard this finding entirely driven by small number where patients appear have been dead on arrival. Conclusions procedure-based approach allows researchers use clinical judgement physician, who saw patient determine likely each may thus provide useful tool investigating beneficiaries.
